BALL-BEARING' FOR WHEELS.

SPECIFICATION forming part of Letters gatent No. 489,133, dated January 3, 1893. Application filed August 29,1892. Serial No. 444,378. (No model.)

To afl/Z whom, t may concern:

Beit known that I, DAVID ROUGHEAD, a :subject ofthe Queen of Great Britain, resid- 1 ing at Buffalo, in the county of Erie and State 5 ot"` New York, have invented new and useful Improvements in Ball-Bearings for Vehiclej Wheels, of which the following is a specification.

i My invention rela-tes to' ball-bearings for vexo hicle wheels in which the balls and the bearing surfaces or cones are carried by the wheelhub in. such manner that the wheel can be re i, moved from the axle spindle like an ordinary wheel without disturbing the balls.

The object of my invention is the production oi' an efficient ball hearing of this kind which is readily applied to wheelfhubs of ordinaryconstruction.

i In the accompanying drawings:-Figure l :12e is a sectional elevation of a wheel hub provided with my improved bearing, showing the hub applied to the axle. Fig. .5 is a similar view showing the hub removed from the/axle. Fig. 3 is a cross section in line wdr, Fig. l.

Like letters of reference refer to like parts in the several iigures.- i

A is the axle spindle, and a the usual eollar or shoulder formed at the inner end thereof. l

B represents the axle box secured within the hub and carrying at eaeb. end a cone or bearing ring b. These cones` are `.preferably separate from the axle box and secured thereto in any suitable manner. j

C (l represent cones arranged on 'the outer sides of the cones D, and forming with the latter annular groovesin which the ballsd are arranged. v Each oi the cones C is formed with a collar @which extends inward through the 4o adjacent cone ci' the axle box and surrounds the axle spindle, as shown in lig. l. Un .the inner ends of the collars care arranged stops f, which, by Coming in Contact with shoulders g at the inner ends of 'the inner cones h, pre- 4,5'` vent the outer cones C from being separated from the inner cones to such an extent as to allow the balls to fall out when the wheel is removed from the axle spindle. These stops preferably consist of screw-nuts applied to the 5o threaded inner ends of the collars c. Each ofthe outer cones C is formed at its outer end i with a cap or inwardly projecting marginal iiange h which overlaps `the adjacent inner cone and excludes dust dse, from thebearin'g surfaces.

-i is an adjusting nut applied tothe outer threaded endo'f the axle spindle and'bearing against the outer side of the adjacent cone C, and j isa jam nut bearing,r `against the outer side of the 'adjusting nutforpreventing loosening thereof. Upon removing these nuts,

the Wheel with its ballbearings can be removed from the axle spindle and again re sse" placed thereon, like an ordinary wheel, Without disturbing any of therbearing cones or spilling the balls, the two sets of bearings remaining intact when the wheel is removed from the spindle, as shown in Fig. 2, as well as when it is on the spindle. The cones are readily adjusted for taking up `wear by loos-` ening the jam nut j and screwing` the adjusting nut :i farther inwardly on the! spindle, whereby both sets of cones are simultaneously adjusted.

My improved bearing does not require a bearing box of peculiar construction, but can be used with a box of ordinary construction, it being only necessary to secure the inner cones of the bearing to the end of the axle-bex and recess the Wooden hub to receive theinner end of such cones, thus rendering the bearing especially applicable to old wheels or vWheels already in use.

. I claim as my invention :MI

l. In a ball bearingA for vehicle wheels the.,

' the combination `with the axle box or bushingarranged within the Wheel hub,`of bearing rings secured to opposite'ends of the axle box and forming the inner cones of the bearing,

-outer cones arranged on the outersides ofthe inner cones and each provided with a collar extending` inwardlythrough the bore of tho adjacent inner bearingring or cone, stopsarranged on said collars, whereby the `outward movement of the .outer cones with reference tothe inner conesis limited, and balls inter.- posed between the inner and outer cones, nul)- stantially as set forth.

In a ballbeariwo`- for vehicle wheels Lee., the combination with the axle bor. or bushing arrangei'l within the" wheel hub, of bearings secured to opposite ends of 'said conforming the inner cones of the beau-ini; and provided with shoulders arranged within the tubular axle box, outer cones arranged on the outer .,sivdes of t'ne inner cones and each having a eollai' extending inwardly through the adjacent 'inner bearing rino' or cone and provided at it's inner end'wi'th aasrew thread, a stop nut applied to each of said threaded eollaijs cm1 the *innen sides of the shoulders'ofhe inner cones',

outer cones of and. balls arranged. between the'nner-and set forth.

. In a. bal] bearing for vehicle wheels, the

ombnafon w1' Lb the axle box, of bearing rings cones secured-to opposite ends ofthe box'and forming the inner cones of the bear-- ing, outei cones arranged adgeeenl'gdo: the in- Jxe bearing, substantially as nel' cones and provided at their 'oufel 'ends with caps Whiclioverlap the innercones,oollars formed on the outereo'nes-and extending through the inner cones, stops' applied to @he innerV ends; of said eollars for limiting txlleouh ward movement of the outer eones, and-balls interposed between said infiel-andeutet con es,

.Substantially as se#J forth.'
